CUTTING AND SCORING ROLL FOR PAPER-BOX,MACH|NES.

SPECIFICATION forming part of Letters Patent No. 562,985, dated June 30,1896.

Application filed October 22, 1895. Serial No. 566,569. (No model.)

To ctZZ whom it may concern.-

Be it known that I, EUGENE H. TAYLOR, a citizen of the United States,residing at Lynn, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Cutting and ScoringRolls for Paper-Box Machines, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention consists in a roll of improved character and construction,provided with means for cutting a continuous strip of material intosuitable lengths or blanks, scoring the said blanks at each side thereofadjacent to the cut edges to facilitate the operation of folding downthe sides or flanges, and notching the said blanks at the cornersthereof; and also provided with devices whereby to enable the cuttersand scorers to be adjusted and the dimensions of the said blanks to bevaried as required.

The invention first will be described fully with reference to theaccompanying drawings, after which it will be more particularly pointedout and distinctly defined in the claims at the close of thisspecification.

Figure 1 of the drawings shows a roll embodying the preferred form of myinvention, the said roll being in elevation for half its length and incentral longitudinal section throughout the other half thereof, bothjournals of the roll and the beveled gear which is carried by one of thesaid journals being represented in elevation. Fig. 2 is a view showingthe roll in end elevation, looking at it from the left-hand side in Fig.1.- Fig. 3 is a view showing the roll in transverse section on thevertical plane indicated by the dotted line 3 3 of Fig. 1. Fig. 4: is aview showing in plan certain features of the cutters and scorers, whichI shall explain hereinafter.

The body of the roll comprises a middle or main portion 1 and the sidepieces 2 2, which are secured to the said middle or main portion in themanner which is explained hereinafter. The main portion 1 is providedwith journals 3 3, one of the latter carrying the bevel-gear 4. or otherdevice through which the roll receives power from a suitable train ofoperating mechanism. 5 5 are cutting-blades extending lengthwise of theroll, and located diametrically opposite each other on the roll.

Adjacent to each of the cutters 5 is a pair of scoring-blades 6 6, onescoring-blade on each side of the cutter. The said blades 6 6 alsoextend lengthwise of the roll. As the latter rotates, each cutter seversfrom the continuous strip or web of material which is fed to the actionof the roll a blank that is of a width corresponding with the distancebetween the edges of the two cutters 5 5 measured along the circle whichis described by the said edges of the cutters 5 5 in the rotation of theroll. At the same time the edges of the scoring devices 6 6 score thesuccessive blanks adjacent to each cut edge thereof, and parallel withthe line of cut, so as to facilitate the op- I eration of turning downthe side portions of the blank. The two groups of cutting and scoringdevices which are carried by the roll, each consisting of a cutter 5 andtwo scorers 6 6 adjacent to such cutter, are represented clearly in thesectional view which is given in Fig. 3. One of the said groups is shownpartially in plan in Fig. l. At the opposite ends of each group,comprising a cutter and two scorers,as just specified, arelocated thenotching-cutters 7 7. One of these cutters is shown in plan in Fig. 4,as well as its relations to the ends of the parts 5 6 6 of one of thegroups aforesaid. The object of the said notchingcutters is, as will beunderstood, to remove portions at the corners of each blank, and thusdispose of the excess of material at such points.

Each notching-cutter 7 comprises a cutting portion extending lengthwiseof the roll in line with each scorer 6, and a connecting portionextending around the roll from the end of one scorer of a group, pastthe end of the adjacent cutter, to the end of the other scorer of thegroup. I Each notching-cutter, therefore, removes a rectangular piecefrom the web of material at the corresponding end of the cut which ismade in the said web by the adjacent cutter 5. A part of the saidrectangular piece comes from one blank, and the other part comes fromthe next adjacent blank, as will be understood.

The notching-cutter 7 has the main portion thereof curved concentricallywith the axis of the roll, as is shown most clearly in Fig. 2.

While I have shown two groups of devices applied to the roll, it is tobe understood that one set alone may be employed, if desired, or

more than two in some embodiments of my invention.

The cutters 5 5 are located in grooves S 8, extending lengthwise of themain portion 1 of the roll. The bottoms 81 81 of the said grooves areinclined from or near one end of the roll to or near the other endthereof. Thus one end of the bottom of each groove is farther from theaxis of the roll than the other end thereof. WVithin each groove isplaced a wedge 9, the outer face of which is parallel with the axis ofthe roll, while the inner face thereof is inclined correspondingly withthe bottom of the groove, but in the opposite direction. The inclinedinner face of the wedge is in contact with the reversely-inclined bottomof the groove, while the inner edge of j the cutter-blade is in contactwith the outer edge of the wedge. Adjustment of the wedge lengthwise ofthe roll will be accompanied by adjustment of the cutter-blade radiallyof the roll, and thereby may be secured the desired radial distancebetween the axis. of the roll and the acting or outer edge of the cutter5. Both of the cutters will be adjusted to bring their cutting edges tothe same distance from the axis of the roll. The making of radialadjustment of the cutters is equivalent to varying the diameter of theroll, and the length of the circular path which is described by the edgeof each cutter in the rotation of the roll will vary proportionately asthe cutter is adj usted toward and from the axis of the roll, so thatthe distance between the cuts and the width of the blanks will be variedaccordingly.

As a convenient means of effecting the longitudinal adjustment of thewedges which occasions the radial adjustment of the cutters, I form orprovide the inclined inner edge of each wedge with a rack 10, and inengagement with each rack I employ a pinion 11 on a short shaft 12. Thedotted lines in Fig. 2 show clearly the pinions 11 11 and the shafts 1212 on which they are mounted. The said shafts extend in oppositedirections transversely of the roll,and are fitted to holes madetransversely in the main portion 1 and through the side pieces 2 2.Around the outer ends of the said shafts 12 12 the holes in the saidside pieces 2 2 are enlarged or counterbored for the reception of theend of a socket-wrench, which may be applied to the squared extremitiesof the said shafts when required, for the purpose of rotating thelatter, and the pinions thereon, and effecting longitudinal adjustmentof the wedges 9 9, as called for in securing the desired radialadjustment of the cutters 5 5. The side pieces 2 2 are secured againstthe opposite sides of the main portion 1 of the roll by means of bolts13 13, (shown clearly in dotted lines in Fig. 3,) the heads of thelatter being received in depressions or recesses, as indicated in saidfigure.

The opposite sides of the main portion 1 of the roll are rabbeted, asshown clearly in Fig. 3, to provide longitudinal recesses or spacesbetween the main portion 1 and the side portions 2 2 for the receptionof the scorers 6 6. The bottom of each space is inclined, as indicatedby dotted lines at 14 14, at the left of Fig. 1, and against theseinclined bottoms 14 14 bear the reversely-inclined inner edges of wedges15 15, which are shown by dotted lines at the left in Fig. 1. Thesewedges 15 15 have outer edges, which are parallel with the axis of theroll, and the inner edges of the scorerblades 6 6 are incontact with thesaid outer edges of the wedges.

The arrangement in connection with each scorer is essentially the sameas that which has just been described as existing in connection witheach cutter. The object is the same, namely, to effect an adjustment ofthe scorer, so that its edge shall stand at a greater or less distancefrom the axis of the roll.

Adjustment of the scorers follows that of the cutter, and will be madein order to maintain the scorers in proper working position relativelyto the cutters and the material which is operated upon.

In connection with the wedge 15 for each scorer I employ devices foradjusting the said wedge longitudinally, and I have shown such adjustingdevices as comprising a rack 16 on the inner edge of each wedge, apinion 17 in engagement with the said rack, and a short shaft 18 onwhich the said pinionis mounted. Each of the said shafts 18 is mountedto turn in a hole through one of the side pieces 2, and the said holehas an enlargement, as at shaft for the reception of a socket-wrench,

which latter may be fitted upon the said squared end, and by means ofwhich the shaft may be turned. The bolts 13 13 pass through holes in oneside piece 2, through holes in the middle-or main portion 1, and throughnotches or slots 20 20 in the inner edges of the cutters and scorers, asindicated in the case of the cutters in Fig. 1, and the threaded endsthereof fit threaded holes in the other side. By tightening up saidbolts 13 13 the parts are drawn together so as to clamp the scorers 6 6between the side portions 2 2 and the main portion 1, and also springthe sides of the grooves 8 8 against the sides of the cutters. By meansof the said bolts not only are the side portions 2 2 secured to the mainportion 1, but the cutters and scorers are all clamped in place securelyin the desired position of adjustment. It will be observed that thecutters 5 5 are located in one plane extending diametrically through theroll, and are adjustable in the said plane toward and from the axis ofthe roll. The scorers 6 6 are adjustable in planes parallel to'the saiddiametrical plane of the cutters.

The object of the radial adjustment of the cutters which has beendescribed is to vary the distances between successive cuts, and therebyproduce blanks of different widths. The adjustment of the scorersaccompanies that of the cutters, and is necessary in order to compensatefor the adjustment of the latter, and to cause the edges of the scorersto enter the material to the proper depth. As will be understood, also,the adjustment of the scorers varies the distance between the twoscorers which act on the same blank, measured along the circular pathwhich the edges describe, and correspondingly varies the distance apartof the scorers which are made alongside the cut edges of each blank.Thereby the width of the blank after its sides have been turned downalong the scores is varied as required. The adjustment of the scorersbeing to the same extent as the adjustment of the cutter and in planesparallel therewith the distance between the cut and the score at eachside thereof does not vary.

The cutters and scorers are readily removable, so that others ofdifferent length may be readily substituted, the notchingcutters 7 beingprovided with adjusting devices by means of which their position on theroll may be varied to suit the length of the cutters and scorers. Eachnotching-cutter 7 is held in place by a bolt 21, the stem of whichenters a slot 22, extending lengthwise of the main portion 1 of theroll, the inner portion of the said slot being enlarged, as at 23,toreceive the enlarged head of the bolt 21. 24 is a nut which is appliedto the threaded end of the bolt 21, it being accessible from theexterior of the roll, as indicated in the drawings, to enable it to bemanipulated at will, as may be required in order to loosen and tightenthe notching-cutter in making adjustment thereof.

The roll constructed as shown in the accompanying drawing is intendedchiefly for use in the production of blanks for the covers of boxes.Such covers, in addition to varying in their lengths, vary chiefly inthe distances or widths between the side flanges thereof, while thedepth of the flanges themselves is not required to vary.

In the construction shown,the notching-cutters are not adjustableradially. Provision for effecting such adjustment as Well aslongitudinal adjustment thereof might readily be made, but I find itconvenient to provide a number of notching-cutters, of sizescorresponding with the variations which it is desired to produce in theeifective diameter of the roll. In fitting the roll for the purpose ofproducing blanks of any desired size, I apply thereto notching-cuttersappropriate for that size, and then adjust the scoring and cuttingknives so as to bring them into proper position. v
